# ICON 01-26 GM 2500/3500 HD 0-1in/07-18 GM 1500 4in Rear VS 2.5 PB CDXS Pair ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. These shocks are configured specifically for each application in both length and damping tune. Like all ICON'S Shock Absorbers, V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. For piggyback and specific remote reservoir applications, ICON'S unique use of a 6061 billet aluminum manifold a few inches below the top cap of the shock creates an internal Bump Zone that when used creates an additional 20% of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. ICON's exclusive Compression Damping Dual Speed (CDXS) valves are included for precisely dialing in your suspension performance. CDXS controls fluid flow under compression, with independent adjustability of high speed and low speed compression force. 10 discreet detented settings for both low and high-speed adjustment knobs allow separate adjustments for handling response and overall aggressiveness. - ICON CDXS equipped for independent adjustability of high speed and low speed compression force for handling response and aggressiveness - One piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road - ICON’s internal “Bump Zone” increases damping by 20% to provide more control as the shock approaches full compression - One-piece impact extruded aluminum cylinders offer excellent corrosion resistance and consistent finish - Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range - Remote reservoir design improves heat dissipation to reduce shock fade during prolonged use - PTFE lined spherical bearings and application specific mounting hardware - 7/8” diameter induction hardened, chrome plated shock shaft - Nitrogen charged monotube design with piggyback reservoir - 6061 aircraft grade aluminum CNC machined components - 100% Rebuildable - 100% Revalveable This Part Fits: Year Make Model Submodel 2016-2018 Chevrolet Silverado 1500 Custom 2014-2018 Chevrolet Silverado 1500 High Country 2009-2013 Chevrolet Silverado 1500 Hybrid 2007-2013,2015-2018 Chevrolet Silverado 1500 LS 2007-2018 Chevrolet Silverado 1500 LT 2007-2018 Chevrolet Silverado 1500 LTZ 2015-2018 Chevrolet Silverado 1500 SSV 2007-2018 Chevrolet Silverado 1500 WT 2010-2013 Chevrolet Silverado 1500 XFE 2001-2004 Chevrolet Silverado 2500 Base 2001-2004 Chevrolet Silverado 2500 LS 2001-2004 Chevrolet Silverado 2500 LT 2004 Chevrolet Silverado 2500 WT 2001-2005 Chevrolet Silverado 2500 HD Base 2020-2026 Chevrolet Silverado 2500 HD Custom 2015-2026 Chevrolet Silverado 2500 HD High Country 2001-2006 Chevrolet Silverado 2500 HD LS 2001-2026 Chevrolet Silverado 2500 HD LT 2007-2026 Chevrolet Silverado 2500 HD LTZ 2003-2026 Chevrolet Silverado 2500 HD WT 2024-2026 Chevrolet Silverado 2500 HD ZR2 2001-2005 Chevrolet Silverado 3500 Base 2001-2006 Chevrolet Silverado 3500 LS 2001-2006 Chevrolet Silverado 3500 LT 2004,2006 Chevrolet Silverado 3500 WT 2015-2026 Chevrolet Silverado 3500 HD High Country 2007-2026 Chevrolet Silverado 3500 HD LT 2007-2026 Chevrolet Silverado 3500 HD LTZ 2007-2026 Chevrolet Silverado 3500 HD WT 2014-2018 GMC Sierra 1500 Base 2007-2018 GMC Sierra 1500 Denali 2009-2013 GMC Sierra 1500 Hybrid 2007-2013 GMC Sierra 1500 SL 2007-2018 GMC Sierra 1500 SLE 2007-2018 GMC Sierra 1500 SLT 2007-2013 GMC Sierra 1500 WT 2010-2013 GMC Sierra 1500 XFE 2002-2004 GMC Sierra 2500 Base 2001-2002 GMC Sierra 2500 SL 2001-2004 GMC Sierra 2500 SLE 2001-2004 GMC Sierra 2500 SLT 2003-2004 GMC Sierra 2500 WT 2020-2026 GMC Sierra 2500 HD AT4 2024-2026 GMC Sierra 2500 HD AT4X 2002-2005,2015-2021 GMC Sierra 2500 HD Base 2011-2026 GMC Sierra 2500 HD Denali 2024-2026 GMC Sierra 2500 HD Denali Ultimate 2022-2026 GMC Sierra 2500 HD Pro 2001-2002,2006 GMC Sierra 2500 HD SL 2001-2026 GMC Sierra 2500 HD SLE 2001-2026 GMC Sierra 2500 HD SLT 2003-2014 GMC Sierra 2500 HD WT 2002-2005 GMC Sierra 3500 Base 2001-2002,2006 GMC Sierra 3500 SL 2001-2006 GMC Sierra 3500 SLE 2001-2006 GMC Sierra 3500 SLT 2004-2006 GMC Sierra 3500 WT 2020-2026 GMC Sierra 3500 HD AT4 2015-2021 GMC Sierra 3500 HD Base 2011-2026 GMC Sierra 3500 HD Denali 2024-2026 GMC Sierra 3500 HD Denali Ultimate 2022-2026 GMC Sierra 3500 HD Pro 2007-2026 GMC Sierra 3500 HD SLE 2007-2026 GMC Sierra 3500 HD SLT 2007-2014 GMC Sierra 3500 HD WT ## Details - **Price:** 2327.47 CAD - **Vendor:** ICON - **Type:** Shocks and Struts ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 2327.47 CAD | In stock | ## Images - Photo - Close Up - Photo - Close Up - User 1 - Technical Drawing - Technical Drawing - Features and Benefits - Logo Image - Logo Image --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/icon-01-26-gm-2500-3500-hd-0-1in-07-18-gm-1500-4in-rear-vs-2-5-pb-cdxs-pair) > Updated: 2026-08-08
